comparison tag for string

[1298509345]

• [x] I have looked at the documentation here first?
• [ ] I have looked at the examples provided that may showcase my question here?

Package version eg. v9, v10:

v10

Issue, Question or Enhancement:

why the comparison tag for string is len(str) why not return str1 >= str2

Code sample, to showcase or reproduce:

baked_in.go
func isGteField(fl FieldLevel) bool {
    field := fl.Field()
    kind := field.Kind()

    currentField, currentKind, ok := fl.GetStructFieldOK()
    if !ok || currentKind != kind {
        return false
    }

    switch kind {
                // ... 
    }

    // default reflect.String // what does this annotation mean
    return len(field.String()) >= len(currentField.String())
}
